Create New Function module and maintain attributes like Remote enabled.
Let us say Example for Sales order,you have some custom fields.
Your ZFM Name like ZBAPI_SALESORDER_CREATEFROMDAT
call sap Standard Function module within your Zfunction module.
Pass the all parameter to SAP Function module and Extension structure ,here we can send the data to Custom Fields.
See the example code below...
FUNCTION zbapi_salesorder_createfromdat.
